Here's your answer (brace yourself):
I won some items in a video game, on the steAm website
I used their market to sell the item, then I purchased Keys from a game called Team Fortress 2 which can be easily exchanged to bitcoin.
I used Dispenser.tf, which is a p2p game item/bitcoin marketplace.
I then withdrew my balance to my Coinomi wallet to the bitcoin address 1GH8EDcBoX56cWn6fkgikQFK4sS25PNr6b.
Next, I sent these bitcoins to Blocktrades, and converted them to STEEM at market rate!
Tah Dah!
